Nice components, but I cann't overclock very well !!! HELP !

Hi, I have these specs:
C2D E6600 + Tuniq Tower 120
EVGA 680i A1 Bios P27
Corsair 9136C5DF (F = with Corsair Airflow Fan)
EVGA 8800 GTX Superclocked
Creative X-Fi Fatality
750 Watts PowerTech
Raid 0 2*360GB WD + LiteOn DVDR DL
2 * 120 MM fans bushing lots of air 94 CFM each(though they sound like jet engines) and keeping the whole system at 28c on Idle and around 48 on full load after 2 hours (running 2 x Orthos full load blend test)
All obove running @ stock speeds and volts

I cann't overclock this machine beyond 3.2 Stable
I thought I would be able to achieve somthing like 3.6 stable, I tried 9x * 1600 = 3600GHz but wouldn't boot
I tried 8x * 1800 = 3600 also wouldn't boot
I tried overvolting a little bit up to 1.4125v but nothing changed
I tried linking, unlinking, 1:1, 3:2, 4:5 settings and I tried the manual settings having the memory to run 1:1 but nothing really worked.
:( 
Sometimes it would boot, but crashes while loading windows....

Any help guys would be very much appreciated. TIA

You may need more than 1.4125V that is what I needed for mine to be stable at 3.2 on a e6400 at 400FSB. Try 1.425 or 1.45 this should still be ok with your cooling. Also try upping your Memory voltage. I needed mine set to 2.0v just to keep the stock speed stable.

Hello everybody... I feel very happy this morning.... and that's because I managed to overclock my rig to 3.4 GHz ===>>> verrrry stable.

I overvolted the cpu core to 1.5v (stock was 1.31 !!!) and the SB core to 1.4v (stock is 1.3) thank you Jay2tall for the tip :) 

the multiplier is 8x and the QFSB is 1700 MHz (1700 / 4 = 425 MHz) and I used that 425 for the memory 425 * 2 = 850 MHz

I tested with 2 instances of Aurthos and monitoring the temps with TAT and Speed Fan (to compare the temps' readings) and the Speeds with CPUz and the voltage readings with nMonitor.
Temps on idle ~ 29
Temps on load after 2 hours ~ 48 :) 

and I enjoyed hours of intense playing on STALKER and FEAR and Supreme Commander.

I believe I can bush it much more ... but I don't think I will really need to do that... every thing plays like a charm.. it's like cutting butter with a hot knife.
Thank you all...

I'm not sure if you can save your overclock settings on your MB but you could try using the x9 multiplier and getting a higher overclock. Since you now know your system needed some more juice it might be worth it to try the native multiplier for your processor. 400*9=3.6Ghz..... and that is a lower bus than you are running now. Just a thought.. If it doesnt work out you now have a stable configuration to fall back on.

WAY TO GO.
